PUMP.

SPECIFICATION forming part of Letters Patent No. 592,570, dated October26, 1897.

Application filed March 22, 1897. Serial No. 628,723. (No model.)

To a/ZZ whom t may c01ccer1/b.f

Beit known that 1, JEREMIAH Lockwoon, a citizen of the United States,residing at Sullivan, in the county of Sullivan and State ofIndiana,have invented certain new and useful Improvements in Pumps; andI do declare the following to be a full, clear, and exact descrip'- tionof the invention,such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention has relation to force or lift pumps for wells, cisterns,and the like, and the object is to produce a pump of this class whichshall be simple in operation and inexpensive in construction; and tothese ends the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

In the accompanying drawings the same referencacharacters indicate thesame parts of the invention.

Figure 1 is a vertical section of my improved pump, and Fig. 2 is adetail View.

1 represents the pump-cylinder,mounted on the legs 2 2, and 3 is anordinary ball-valve located in the bottom 4t of said cylinder. 4

5 represents the plunger or piston, which is provided with an ordinaryball-valve 6. The upper face of the bottom 4. is conically inclinedtoward the valve-seat to facilitate the seating of the valve by gravity.

8 represents the cylindrical piston-rod, its lower end connected by abracket 9 to the piston.

10 represents the closed top of the pumpcylinder, and it is providedwith a valve 12, covering an orifice 13, and having a diagonal arm 14,provided with a weight 15, which nor mally holds said valve closed.

16 is the dischargefspout, its upper end terminating in the gooseneck17.

18 represents a horizontal bracket having the diagonal foot-braces 18',which forms a support for the discharge-spout, and it is provided with arectangular orifice 19, forming a guide for the rack 20, whichconstitutes the upper end of the piston-rod.

21 represents a friction-sleeve mounted on the cylindrical body of thebolt 22, eccentrically mounted in the bracket 18,and said sleeve formsan adjustable bearing for the plane back of the rack.

`23 represents a segmental gear-wheel journaled on a bolt 211in thebracket 1S and having its teeth in mesh with the teeth on the rack 20.

25 represents the pumphandle,fxed to segmental gear-wheel, and when saidhandle is vertically reciprocated the gear 23 is oscillated and thepiston reciprocated in the pumpcylinder, which raises the water in theusual well-known manner.

In the ordinary manipulation of the piston its upper end does not comein contact with the arm 14 of the valve 12; but if the handle be moveddownward to the full limit of its stroke it raises the piston againstthe arm 14 and opens the valve 12, so as to let the column of water inthe discharge-pipe iiow back into the well and thereby prevent thedanger of freezing in the pipe. y

Although I have specifically described the construction and relativearrangements ofthe several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

A pump comprising the discharge-pipe 1G, the cylinder 1 connected to thelower end thereof and provided with the inlet-valve 3 and theoutlet-valve l2, the piston 5 provided with the valve 6, and thepiston-rod 8 having its upper end terminating in the rack-bar 20, incombination with the bracket 18, the segmental gearwvheel 23 journaledin said bracket and in operative connection with said rack, and providedwith the handle 25 and the friction-sleeve 21 eccentrically mounted insaid bracket to form an adjustable bearing for the rack-bar, whereby thewear on the gear and rack may be taken up, as and for the purpose setforth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
